SPECIFICATION forming part of Letters Patent No. 451,264, dated April28, 1891.

Application filed October 2. 1890. Serial No. 366,909. (No model.)

To all whom. t may concern:-

Be it known that 1, SAMUEL Y. BUCKMAN, a citizen of the United States,residing` in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Apparatus for CoatingMetal Plates with Tin or Alloys rl`hereof,which improvement is fully setforth in the following specification and accompanying drawings.

My invention relates to improvements in apparatus for coatingsheet-metal plates with tin or alloys thereof; and it consists of anapparatus composed of devices each of which is adapted to performa'separate step in the process, the respective devices having operatingmechanisms so connected that the plates to be coated are received at oneend of the apparatus and automatically passed through the same, beingcleansed,united, coated, burnished, and wound in rolls of such lengthsas desired.

It further consists of the combinations of parts, substantially ashereinafter described.

Figures 1, 2, 3, 4, 5, G, 7, and 8 represent a vertical section of anapparatus for coating sheetmet-als embodying` my invention. Fig. 9represents a plan View of a section of the main shaft and a secondaryshaft with connecting gearing and clutch. Fig. 10 represents an end viewof the parts shown in Fig. 9. Figs. 11, 12, and 13 represent plan viewsof the main and a secondary driving-shaft for the operating mechanism ofthe cleansing and drying devices and the feed-rollers. Fig. 14represents a plan view of main and secondary shafts with operatingmechanisms for the edging device. Fig. 15 represents a plan view ofoperating mechanism for the b u rnishing device.

Similar letters and numerals of reference indicate corresponding partsin the several figures.

Referring to the drawings, A designates a scouring device, the sameconsisting of two boxes 1 and 2, having the guides 3 therein,in whichthe plates B to be coated are held While being passed through thedevice. The

said boxes are provided with rotary brushes 4 et and 5 5, as shown,thebrushes of each set rotating in opposite directions.

6 6 designate chutes leadinginto the boxes 1 and 2 for conveying sand orother scouring material to the brushes.

.C designates a spraying device consisting of a box 7, having openingsin its ends for passing the plates of metal into and from the same, andabove and below the guides 8 therein are pipes 9 9, having perfor-ations10, so that water fed from any suitable supply can be sprayed on bothsides of the plate at the vsame time.

B designates a drying device consisting of drying-rollers 11 11., havinga rubber coating, and the felt-covered rollers 12 l2, each of the latterhaving steam-jaokets13 for drying thc said felt covering.

The above parts-viz., the scouring, spraying, and drying devices-are notmore specically described hereimbeingper se no part of this invention,and the same are more fully described and claimed in an application forLetters Patent for improvement in apparatus for cleansing sheet-metalplates, led September l1, 1890, Serial No. 364,089.

E designates an edging or folding device for securing the ends of theplates of sheet metal together, so as to form a continuous sheet of thesame, and consists of two formers 14 15, provided with toggle-levers 1616, Which are operated by the rotation of the cams 17 17 on the shafts18 18, so as to force the formers against the rear end of the frontplate and the front end of the rear plate in such manner as to form bentportions adapted to be hooked together and seamed when brought intocontact. W'orm-wheels 19) on the said shafts 18 engage with Worms 19 onthe main shaft P of the apparatus for operating said shafts 18, andthereby the cams 17. This specific edging device, per se, is also madethe subject of a separate application, and is not,

therefore, more fully described herein, being completely set forth,illustrated, and claimed in an application for Letters Patent, SerialNo. 369,160, filed october 24, isoo.

F designates the coating device, consisting of a dipping-pot G, havingan entrance-limb 20 and an exit-limb 2l, with the guides 22 therein. Agrease bath H receives the sheet before its passing into the limb 20,and a grease bath J is adapted to receive the said sheet, if necessary,as itleaves the pot. Squeezing-rollers 23 regulate the thickness of thecoating as the sheet emerges from the coating material.

IOO

The dipping-pot herein shown is described and claimed in an applicationmade by me of date August 30, 1890, Serial No. 363,498.

K designates a burnishing device consisting of a number of wheels 24,suitably mounted and having a peripheral surface adapted to polish orburnish the faces of the coated sheet.

L designates a cutting device, which is provided with suitable operatingmechanism of any well-lnown character, and which being of any ordinaryconstruction is not more fully described herein.

N designates a device for reeling the sheets when cut on two separatedrums, and consists of a pivoted table 25, on which the sheetwis adaptedto travel, and which rests upon a rotary eccentric or cam 26 on a shaftoperated by the main driving-shaft and adapted to raise or lower thetable, so that the sheet thereon may be fed alternately to either anupper drum 27 or to alower drum 2S. Placed convenient to the severalnamed devices are adjustable feedingrollers M of any wellknownconstruction.

The scouring, drying, coating, edging, burnishing, cutting, and reelingdevices herein described are each connected with the main driving-shaftP, so as to be operated thereby, and the feeding-rollers M, in advanceof the edging device, are operated from asecondary driving-shaft S,having a clutch R, with operating mechanism consisting of a groovedcam-wheel 31 on thc shaft 18, a pivoted lever 32, having an endconnected with and operated by the rotation of said wheel 31 and an endconnected with and operating a detent 32X, fitted in the sleeve 33 ofthe clutch mechanism, said sleeve being fixed on the secondary shaft S,so as to rotate therewith. A loose gear-wheel 34, mounted on t-he saidshaft S, meshes with a gear-wheel 35, rotatably secured to the mainshaft I. A bevel gearwheel 3G, mounted on the shaft S, meshes with thebevel gear-wheel 37 on the shaft 88 of feed-roller M, and therebyoperates the same. It will be seen that as the detent 32X is moved so asto engage with the clutch R the shaft S isrotated by the rotation of themain shaft P, and when the said detent is disengaged from said clutchthe shaft S does not receive motion. The feeding-rollers M, in the rearof the edging device, are operated from a secondary shaft Q, which alsohas a clutch connection (not shown) with operating mechanism connectedwith the main shaft similar to the clutch connection and operatingmechanism hereinbefore described, said parts being so timed andconnected as to automatically and consecutively operate the severalparts, as follows: A plate of sheet metal is passed between thefeed-roller M at one end of the apparatus, and so enters the scouringdevice, being held in the guides thereof. The advance end of the platepassing from the said scouring device is drawn into the spraying andthen into the drying devices, after which it is passed to the edging orfolding mechanism. The advance plate is passed through the said foldingdevice until its rear end is above the second former 15, when the frontend of the following plate is above the former 14, each succeeding platebeing fed at such intervals to theapparatus. The secondary shafts Q andS, which operate the feeding-rolls so as to advance the plates, are thenstopped by means of their clutch connections, and the mechanismoperating the formers are then put in motion,so as to open the tog-'gle-levcrs 16 and force the formers 14 15 in contact With therespectiveends of theplates, so as to form hooks on the same, as shown in Fig. 4.The formers are then lowered, so as to be free from the plates, and theshaft Q is again put in operation, so that the rear plate is advanceduntil its hooked front has reached the hooked rear end of the firstplate, when it readily unites wi th the same. The secondary shaft S isthen operated by means of its clutchconnection with the main shaft, soas t0 advance the sheet thus formed. It will be seen that the clutchmechanism of the shaft Q is so operated as to connect its shaft with themain shaft slightly in advance of the time of the operation of theclutch of the shaft S, so as to advance the rear plate and permit itsunion with the front plate before thc feed rollers advance the sheetthus formed. The sheet is now advanced until the end of the rear plateis above the former 15, when the shafts Q and S are stopped. In themeantime the first plate of the sheet has passed through the grease bathH and into the dipping-pot, and a new plate has been fed to the scouringdevice. Then the rear end of the sheet is above the former 15, thefrontend of the new plate is under the former 14, whereupon theoperation is the" same as has been described. The sheet on leaving thedipping-pot is squeezed between the rollers 23, so as to regulate thethickness of the coating, and is then passed into the cooling andburnishing chamber K, after which it is passed through the cuttingdevice L and along on a pivoted 'table 25, on which it is guided toeither one of two drums 27 or 2S, according as the table is raised orlowered by the rotary cam 2G. It is wound on said drums in lengths cutby the cutting device L, according as desired, and which may beregulated by any ordinary mechanism suitable for that purpose.

rFhe devices herein described are placedin the order as shown, and maybe either on the one door or ground or on different floors, as shown inthe drawings, the devices in Figs? and 8 being on an upper door, thesheet B passing over a carrier-wheel 29 to the burnishing device. Theshafts which operate the mechanisms on the said upper door are connectedwith the main shaft, so as to be rotated thereby. i

In the drawings the operating mechanisms for the cleansing, drying, andreeling devices IOO IIO

are shown as connected with the main driving-shaft; but it is evidentthe said devices may be operated by mechanisms connected with thesecondary or other suitable drivingshafts, suchlast mechanisms not beingclaimed herein, and, forming no part, per se, of this invention, are notshown or described herein, as any Well-known or usnalmechanism can beused.
